I'm following the comparison threads here since more than a year (thanks Zombie!). I'm a 3D fan (I have more than 50 3D blu rays) and therefore I'm searching for the 'best possible' 3D experience. Just wanted to share a few experiences with you which might be of interest. I own the following projectors and screen:
-Benq W1070 (since 1 week now)
-92 inch, white 1.1 gain.
I think I'm not wrong saying that most of the readers here agree that the Benq W7000 is a very good 3D projector. I like that it is cross-talk free and very sharp. However for me there is an ambivalence in the motion-handling. Especially for 3D IMAX movies which have mostly slow panning camera movements (and therefore no blurr) the frame interpolation performs really well delivering a very smooth real-life experience. However, when I whatch 'Avatar' for example or 'Hugo' there are quite some scenes with very fast camera movement or high speed object movement before a background (for example the scene where Jake Sully is flying for the first time falling from the cliff or Hugo running through a corridor with fast camera panning) and there the frame interpolation does not perform that well showing some strange artifacts (blocks etc.). And this even happens with FI set to 'low'. Do not get me wrong: This is only happening in a few scenes and some may not even notice this, but I'm very sensitive to this and it really is a big drawback of the W7000 for me. Also sometimes the movements of people just doesn't look 'natural' anymore when FI is enabled. 'Just turn it off then', you might say. Yes, but since the W7000 has 60Hz per eye resulting in a 3:2 judder pull-down this is not an option either for me.
Now, for the HW50: What I like about it is its very bright image (even when I set glasses brightness to max-1, it is clearly brighter than the W7000 behind the glasses). What I like further compared to the W7000 is the motion handling (48Hz, therefore no 3:2 pull-down). However what I don't like is the flicker which tires your eyes with time. But this is only a minor drawback for me. What is still the biggest drawback for me with the HW50's 3D is the ghosting (execpt from that it would be quite perfect). It is still too much for my taste (even with glasses set to max-1, and I don't notice a clear improvement when reducing glass brightness further). There are some movies where this is not critical, but even in 'Avatar' which is not famous to be very ghosting-critical, there are some scences where it is very obvious (often bright lights in the background). I also have the 'Monster Vision' glasses and I experimented with them quite some time. The problem is that when I'm able to reduce ghosting at the top of the image then there is some more ghosting at the bottom. Further I don't like that the monster glasses have a very critical viewing angle. If I turn up my head only a bit, then there is far more ghosting visible.
Now to the Benq W1070: Even though this only costs a fraction of the other two machines it really convinces me in the (my opinion) most important aspect of a high quality 3D experience. Yes, it might be not the brightest (quite comparable to the W7000) and yes, it's placement flexibility is quite bad (not good for HP screens) and yes it is louder than the HW50 (which is VERY quiet), but comparable to the W7000. BUT: the picture has that very nice DLP sharpness (eventhough the optics is not the best), it is as clean from cross-talk than the W7000 and it does exceptionally well in the combination of motion handling/flickering: There is no need for FI because it shutters with a multiple of 24fps, so motion is as natural as with the HW50 but there is no flickering either!! I don't know how this is done (some say that it might shutter with 144Hz triple flash in the Benq W1070 threads in other forums, this is still not clear). However, the 3D is VERY gentle to the eyes with this projector and at the same time very natural (no FI neede). I think this combination is quite unique at this time and I personally think this is my new 3D favorite! It's hard to believe that projector which is that cheap pricewise delivers such a high quality 3D image. Furthermore I was very surprised about the contrast: As there is the Texas Instruments darkchip 3 DLP chip in the Benq W1070 its blacks and contrast is at least in pair if not better than that of the W7000, which has only a darkchip 2.
For me, the W1070 clearly outperforms the W7000 in every aspect that is important for me for a natural, sharp and artifacts free 3D-image. A projector which might have very similar strong points as the W1070 might be the Mits HC8000 (from what I read in this threads, since it is DLP as well and can shutter with a multiple of 24fps which is very imporant in my eyes).
I'm wondering what you guys think about those aspects?
